Accident avoidance system onboard a host vehicle includes a position determining system for determining position information for the host vehicle based on signals received from a plurality of satellites, a transmitter for broadcasting the position information for the host vehicle to locations remote from the host vehicle, a receiver for receiving a traffic information broadcast from an infrastructure system including vehicle position information received from position-reporting vehicles and vehicle position information received from an active position determining system that acquires position information for non-position-reporting vehicles, and an accident risk warning system. The risk warning system alerts an operator of the host vehicle of a risk of an accident involving the host vehicle based on the vehicle position information for the host vehicle and map data representing a roadway that the host vehicle is approaching or traveling on including edges or lane boundaries of the roadway.

The invention claimed is: 1. An accident avoidance system onboard a host vehicle comprising:a position determining system for determining position information for the host vehicle based on signals received from a plurality of satellites;a transmitter coupled to the position determining system for broadcasting the position information for the host vehicle determined by the position determining system to locations remote from the host vehicle;a receiver for receiving a traffic information broadcast from an infrastructure system including vehicle position information received from the transmitter of position-reporting vehicles and vehicle position information received from an active position determining system that acquires position information for non-position-reporting vehicles, the position information received from the infrastructure system comprising a subset of available position information including prioritized position information for the host vehicle based on the locations of the host vehicle and other vehicles; andan accident risk warning system for alerting an operator of the host vehicle of a risk of an accident involving the host vehicle based on the position information for the host vehicle determined by the position determining system and map data representing a roadway that the host vehicle is approaching or traveling on including edges or lane boundaries of the roadway and the traffic information broadcast received by the receiver.
